I forgot to add: At least increase is 0.01BTC
Can you prove the ownership of the account with a bitcoin signed message?
Interested on this too
What makes me laugh though, those who ask these questions rarely buy so it does make me wonder why do they ask. Suppose it is because they care about the community not nothing to do with wearing a signature. The question will surly come from someone who wants to buy.
Well the people who do buy rarely ask, and I think they don't ask because of ignorance. There have been a number of cases of people buying an account that later had someone come back claiming it was hacked recently so the question is far from unimportant......since the recent rise in these claims there has been only a very slight increase in the number of people asking for signed messages when they buy accounts so IMO the inquiry is necessary and when they respond to the negative the warning that the account may be hacked is appropriate
